STREET-PAVING.

Specification of Letters Patent.

Application filed May 13 1912.

Patented Nov. 18,1913.

Serial No. 696,880.

To all whom it may concern:

Be it known that I, JAMES Bamvnu.,citizen of the United States, residing'at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Street-Paving, of which the following is a specification.

This invention pertains to an improvement in street paving, and consists in a pres sure absorbing strip adapted to be inter posed between the pavement proper and the curbing to relieve pressure when the pavement expands under the influence of beat, all as shown and described and particularly pointed out in the claims.

In the accompanying drawings Figure 1 is a perspective view of a section of pavement and curbing embodying my invention between the same, and Fig. "2 is a perspective view of one of the cushioning strips or pieces representing the invention in one of its possible forms.

As above indicated, the invention involves an expansible cushioning device for paved streets.

It is well known that where suitable stone or equivalent curbing is used along with brick or stone or equivalent pavement there always is a tendency for the pavement to swell or bulge at some point or other to accommodate the natural expansion and which is liable to be considerable, especially on hot summer days. and which can not find relief at the curbing. Various unsatisfactory attempts ha ve been made to overcome or avoid this condition and which is inevitable if the blocks or bricks are built compactly against the curb stone. I have therefore invented the strip herein shown and which for the present and preferably has a fairly solid body Z) wholly or mostly of asphalt and containing a suitable core a which may be of wire fabric or wire strips or pieces embedded therein or the equivalent of these, the idea being to make a strip which in itself is more or less flexible at all times and adapted to be fairly rigid for handling and which will give character and quality to the strip which it can not possess without some such internal and sustaining portion. Of course the said reinforcement need not neeessarily be of metal but in any event it must have sustaining value for the asphalt or body portion of the strip, and the said strip is shown as having the same depth as the paving block or brick and say an inch or so in thickness and placed next to the curb d. The length of the said strip or piece is not really material but a length proportioned as shown gives very good satisfaction and the said strip of course becomes a permanent portion of the pavement. The opposite ends of the strip are beveled or tapered to pro vide angular faces 0 in the same parallel planes so that overlapping joints may be obtained in laying the strips end to end. The strips are flexible to admit of their use on short curves, as at street corners, and are sold as separate articles of manufacture and use. Their use saves time, labor and expense in the laying of street paving. as well as having the advantages hereinbefore set forth.

lVhat I claim is:

1. As a new article of manufacture and sale, a street paving strip adapted to be interposed between the curbing and paving blocks. the same consisting of asphalt molded to the desired shape and size and having a flexible reinforcing metallic core.

2. As a new article of manufacture and sale, a flat sided strip of flexible asphalt adapted to be used between the curb and the paving and having a flexible. metallic core and oppositely beveled ends adapted to overlap the ends of adjacent strips.

A preformed expansion joint strip comprising an elongated strip of asphalt or equivalent material of substantial thickness provided with a flexible reinforcement em bedded therein.

In testimony whereof I ailix my signature in presence of two witnesses.

JAMES BANWELL.
